I rushed my post and you may have misread it. We are only debating semantics here - choice of words. AWD is generally marketed on vehicles without a low range, where as full time 4wd GENERALLY is used to describe such a vehicle with a low range and a lockable centre diff. A perfect example of an exception to this is Honda who has "4wd" pilots, etc.
You might think your full time 4wd is more bad ass then some AWD import/domestic but really your just buying into the marketing these different brands use. There is no technical-legal definitional difference between full time 4wd and AWD.
All full time or AWD vehicles employs a torsen centre diff, or a planetary gear set to allow for wheel slip between front and rear.
